It's pretty self-explanatory.
NOTES: there are some labelling errors on this image that I have fixed in the zip file version.
a) a word missing in the big circle Re: Regularity? "How many people (DOES) a regularity reach?"
b) "Collab with the most contributions" is used twice with two different stats (I think the second is supposed to say "least")
c) Also, should it be "Most frequent requests made *for*" and "Least frequent requests made *for*"
